Title: Masao Shiota: Innovator in Electron Beam Welding and Heat Transfer Technology

Introduction

Masao Shiota is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of welding and heat transfer technology. With a total of 2 patents, his work has been instrumental in advancing industrial processes.

Latest Patents

Shiota's latest patents include an innovative electron beam welding method. This method is capable of restoring toughness even when high heat input welding is performed. The process involves forming a first weld bead that includes a groove at the butt portions of two base materials. Additionally, it features the formation of a second and third weld bead, which have a narrower width than the first, at predetermined positions. These beads are symmetrically centered about the butt portions and utilize a lower heat input than that used during the formation of the first weld bead.

Another notable patent is the heat transfer tube support structure. This invention aims to prevent the deterioration of reliability and durability in heat transfer tubes. In a steam generator, the support structure includes heat transfer tubes and tube support plates with insertion holes. The design incorporates support portions for the heat transfer tubes, formed in the intermediate portions of the inner surfaces of the insertion holes. The regions between the support portions and the open ends of the holes are designed with inclined surfaces that direct outwardly toward the open ends.
